JSP page request trough round-robin balancer return 404

We're using an instance of Weblogic as a load balancer, and then 2
more instances as managed servers behind it. In there's a file called
PopupDialog.jsp, which is used to display ‘popup' screens in the web
browser. It's fairly simple.
The problem we're having is that when run using the load balancer,
requests for this file responds with a 404 not found error from the
load balancer itself. We can't see that the requests even make it
through to the managed servers. When run directly against the managed
server, everything works as expected.
Any solution? Thanks in advance, Ints
